If going with the same bino but 8x vs 10x the 8x will typically be brighter, larger exit pupil which will help in low light, and wider field of view. I would say for distances within 100 yards I would go 8x assuming use in thick woods. Past 100 yards and a bit more open I would choose the 10x.
I have the B2 11x45s, they are great low light and for seeing lines on archery targets. But much bigger on the chest and smaller field of view.
For comparing B3 or B1.2 they are both optically great looking for the price. B3 will be larger field of view. B1.2 is better low light. Mid day they will not lool much different.
I have 10x42 B1.2 ordered for my wife with custom shop options. We have C1 8x42, B3 8x30, B2 11x45, and B5 18x56, CS1 spotter. Lots of Maven in the family. Lol and brother in law has the c series 10x28 and range finder. I honestly could be happy with any of them for archery hunting. Scouting and rifle hunting where ranges extend I go for the 11s on chest and 18s on tripod.
